Is An interior angle of a triangle and one of its adjacent exterior angles supplementary?
always
An exterior angle of a triangle is equal to the adjacent interior angle?
No. It is equal to the sum of the opposite interior angles.
How do you use the exterior angles of a triangle to find interior angle measurements?
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
What is the Sum of an exterior angle of a triangle and its adjacent interior angle is called?
They are called supplementary angles.
How do you work out the exterior angle of a triangle?
Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.
What are Remote interior angles?
Are two angle of a triangle that are not adjacent to the exterior angle
The angles of a triangle that are not adjacent to a given exterior angle?
Remote interior angles

Can the exterior angle of triangle be straight angle?
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
What is the Sum of an exterior angle of a triangle and its adjacent interior angle is called?
They are called supplementary angles.
Does An exterior angle of a triangle equals 180 minus the adjacent interior angle?
Yes it does. Good work!
